通常，在SOA中，不存在能够执行给定任务的单个服务，但存在能够执行该任务的服务组合。在不断变化的世界中，手动服务组合是不现实的，全自动组合过程也是不现实的：让用户指定他的请求、按下神奇的按钮并等待完美的解决方案是不现实的。我们认为，在合成过程中需要一定程度的用户参与，同时在需要时提供自动化。本文概述了一种以用户为中心的方法，用于将服务组合成最接近用户特定需求的复杂流程。我们区分了两个阶段：服务能力级别的自动组合和用户根据自己的特定需求(如不同粒度级别的领域特定的Qos参数和流程结构)改进组合的贡献。
Frequently, in SOA, there exists no single service able to perform a given task, but there is a composition of services that can. In a continuously changing world, manual service composition is unrealistic and so is a fully automatic composition process: it is unreal to have a user specifying his request, pressing the magic button and waiting for the perfect solution. We believe that a certain degree of user involvement is required during the composition process while offering automatization when needed. This paper presents the overview of a user-centric approach for composing services into complex processes that are closest to the user's specific needs. We distinguish between two phases: the automatic composition at the service capability level and the user's contribution in refining the composition according to his specific requirements like domain specific QoS parameters at different granularity levels and the process structure.
